etched foil mtg cards Jeweled Lotus (Foil Etched) [Commander Masters] you may search your library for an instant or sorcery card with mana value 2 or less Sram, Senior Edificer (Foil Etched)

As its an Uncommon, it should be fairly easy to trade for

The powerful Silverfur Partisan is a three-mana 2/2 that makes it so that people take damage if they target your creatures, and Kessig Cagebreakers create a horde of Wolf tokens whenever they attack too

This can happen one of two ways: (1) the door becomes unlocked on the battlefield or (2) the door becomes unlocked as the Room enters the battlefield because you cast the corresponding half

The fact that it went out of print and is no longer supported doesnt matter and thankfully they printed so much of this game its actually quite easy and cheap to get a hold of a complete collection

You do it all the time for removal, so why not for Swan Song
